The full extension is a super help in baking. Can be attached also easy. What I do not, however, could so easily find out was whether this is a standard unit, which fits into any Bosch oven. I have now bought the extract at random and it fits.
It would be nice if you could provide more information about the full extension here. Therefore, for the purchase / seller 4 stars, for the full extension 5 Stars.
PLEASE NOTE: Sheet metal and rust are not there !!
